Safe Flame Retardants Make Way for Progress

(Swiss Federal Laboratories for Materials Science and Technology, July 22, 2013)

Empa researchers have found an alternative way to produce non-harmful flame retardants with synthetic materials. Tri(chloropropyl) phosphate (TCPP) or some polybrominated diphenyl ethers (PBDE) are most likely harmful to our health, the environment, and may have hormone-like effects that could be carcinogenic. Thus, Empa researchers have developed a project in tandem with the Swiss company FoamPartner which is sponsored by the Commission for Technology and Innovation (CTI.) By synthesizing several substances and adding them to the polyurethane foam, an increased concentration can be obtained. Initial results indicate that the flame retardants do not have negative effects on the foam manufacturing process. As a result, conventional agents that are harmful to health and the environment may soon be a thing of the past. Research results have been accepted by the professional journal Industrial & Engineering Chemistry Research and authorized for publication.
